API standard 650 mechanically-anchored steel tanks repairs to welds

Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API standard 650 mechanically-anchored steel tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API standard 650 mechanically-anchored steel tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.

Allowable Design Stresses
The maximum allowable design stresses for the API standard 650 mechanically-anchored steel tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.
